11. A method for expanding configuration information including a previously defined configuration group, the configuration group including a configuration group name and configuration information, the method comprising, for each piece of configuration information: a) determining whether or not the piece of configuration information is an instruction to apply the configuration group; and b) if it is determined that the piece of configuration information is an instruction to apply the configuration group, then replacing the piece of configuration information with the configuration information of the configuration group.
12. The method of claim 11 wherein the act of determining whether or not the piece of configuration information is an instruction to apply the configuration group is based on whether the piece of configuration information includes the configuration group name.
13. The method of claim 11 wherein the configuration information is arranged in a hierarchy, and wherein if a given hierarchical level of the configuration information includes at least two instructions to apply at least two different configuration groups, then the order of the at least two instructions in the configuration information will determine which one of the at least two different configuration groups will be applied.
14. The method of claim 11 wherein if it is determined that the piece of configuration information is an instruction to apply the configuration group, then further displaying, with visual emphasis, the configuration information of the configuration group; and c) if it is determined that the piece of configuration information is not an instruction to apply the configuration group, then displaying the piece of configuration information.
15. The method of claim 14 wherein if it is determined that the piece of configuration information is an instruction to apply the configuration group, then, further displaying the group name of the configuration group.
16. The method of claim 11 wherein the configuration group consists of a group name and a plurality of configuration statements.
17. A machine-readable medium having stored thereon configuration information for use by a data forwarding device, the configuration information comprising: a) a configuration group including i) a configuration group name, and ii) configuration information; and b) target configuration information including, at a particular point in the target configuration information, an apply group instruction which identifies the configuration group name.
18. The machine-readable medium of claim 17 wherein the target configuration information is arranged in a hierarchy.
19. The machine-readable medium of claim 18 wherein the configuration information arranged in a hierarchy includes container configuration statements and leaf configuration statements, thereby defining the hierarchical arrangement.
20. The machine-readable medium of claim 17 wherein the configuration information of the configuration group includes a wildcard expression, the wildcard expression including a wildcard pattern part and associated wildcard configuration information, and wherein if an existing statement in the target configuration matches the wildcard pattern, then the wildcard configuration information from the wildcard expression is to be applied to the existing statement.
21. The machine-readable medium of claim 17 wherein the configuration group consists of a group name and a plurality of configuration statements.
22. A data forwarding device comprising: a) a data forwarding table; b) a forwarding facility for forwarding data based on information in the data forwarding table; c) a storage facility for storing configuration information for use in the operation of the data forwarding device, the configuration information comprising: i) a configuration group including A) a configuration group name, and B) configuration information; and ii) target configuration information including, at a particular point in the target configuration information, an apply group instruction which identifies the configuration group name.
23. The data forwarding device of claim 22 further comprising: d) interfaces for receiving and transmitting data, wherein the configuration information includes statements to configure the interfaces.
24. The data forwarding device of claim 23 wherein the configuration information of the configuration group includes statements to configure the interfaces.
25. The data forwarding device of claim 23 wherein the configuration information of the configuration group is applied conditionally, based on at least one characteristic of the interfaces of the data forwarding device.
26. The data forwarding device of claim 22 further comprising: d) a routing facility, wherein the configuration information includes statements to configure the routing facility.
27. The data forwarding device of claim 26 wherein the configuration information of the configuration group includes statements to configure the routing facility.
28. The data forwarding device of claim 26 wherein the configuration information of the configuration group is applied conditionally, based on at least one characteristic of the routing facility of the data forwarding device.
29. The data forwarding device of claim 22 wherein the configuration group consists of a group name and a plurality of configuration statements.
30. A machine-readable medium storing an instruction set for configuring a data processing device, the instruction set comprising: a) a first command supporting user input of a configuration group, the configuration group including i) a configuration group name, and ii) configuration information; b) a second command supporting user input of a target configuration; and c) a third command supporting user input of a point in the target configuration to inherit the configuration information of the configuration group, wherein the third command supports user input of an apply-group instruction, which identifies the configuration group name, at the point in the target configuration.
31. The machine-readable medium of claim 30 wherein the first command supports user input of a wildcard expression as configuration information, the wildcard expression including a wildcard pattern part and associated wildcard configuration information, the instruction set further comprising: d) means for applying the wildcard configuration information from the wildcard expression to an existing statement if the existing statement in the target configuration matches the wildcard pattern.
32. An apparatus for expanding configuration information including a previously defined configuration group, the configuration group including a configuration group name and configuration information, the apparatus comprising: a) means for determining, for each piece of configuration information, whether or not the piece of configuration information is an instruction to apply the configuration group; and b) means for replacing, for each piece of configuration information, the piece of configuration information with the configuration information of the configuration group if it is determined that the piece of configuration information is an instruction to apply the configuration group.
